The Influence of Specific Bioactive Collagen Peptides on Body Composition and Muscle Strength in Middle-Aged, Untrained Men: A Randomized Controlled Trial.
Quick Facts
What This Study Found
Collagen peptide group saw a 2.4 kg increase in fat-free mass and a 1.2 kg decrease in fat mass compared to placebo.
Key Numbers
How They Did This
A randomized controlled trial with 97 participants divided into three groups receiving different supplements during a 12-week resistance training program.
Why This Research Matters
This research highlights the potential of collagen peptides as a supplement for improving body composition and muscle strength, particularly in middle-aged men who are untrained.
What This Study Doesn't Tell Us
The study focused only on middle-aged, untrained men, limiting generalizability to other demographics.
